Hi KettFit and welcome to the forum.
I don't know how much you have learned already, but a misunderstanding for many new Type 2 diabetics is that they think it's all about cutting sugar and also that lots of vigorous exercise is also good.
The truth is that all (digestible) carbohydrates are turned into glucose when we digest them. So that mean starches as well as sugars. The starches to keep an eye on are in potatoes, bread, biscuits, pasta, rice, breakfast cereals etc. The sugars are not just added table sugar, but honey, fruit juice and tropical fruits. I just read somebody saying they were surprised by high Blood Glucose after eating a 'light breakfast of cereal and a banana' - light, yes, but guaranteed to test our insulin response !
Likewise, while moderate exercise lowers Blood Glucose (by using it up), if vigorous exercise lasts for more than a minute or so it can cause high Blood Glucose by encouraging the liver to dump more glucose into the blood stream for energy.
I don't know how much (if any) of that will be covered on your DESMOND video. In the past DESMOND courses had a poor reputation depending upon how up to date the person teaching them was.
